BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 614,987, dated November29, 1898. Application filed November 17,1897. Serial No. 658,853. (Nomodel.)

T0 at whom it may concern.-

Be it known that I, JAMES B. RYAN,a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Bed-Bottoms; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to the so called double-decked spiral-springbed-bottoms; and it consists generally in such a bed-bottom comprising asuitable base, a lower horizontal series of vertically disposed spiralsprings, preferably of helical form, connected to and rising from thebase, an upper horizontal series of vertically disposed spiral springs,preferably of double helical form, which are separate from the lowerseries and have their upper ends suitably connected together, and aflexible horizontal fabric of woven, laced, or linked wire interposedbetween the lower and upper series of springs and suitably connected tothe contiguous ends thereof,the said fabric being adapted to steady andeffectually prevent the lower and upper series of springs from movinglaterally or wabbling when weight is imposed upon the bottom and beingalso adapted to permit each of the lower springs to give independent ofthe springs around it when weight is imposed on the particular spring orsprings above it, which contributes materially to the springiness, andconsequently to the ease, of the bottom.

The invention also consists in the construction hereinafter described,and particularly pointed out in the claims appended.

In the accompanying drawings, Figure 1 is a plan View of myimprovedbed-bottom in its operative position with parts broken away. Fig. 2isatransverse section of the same, and Fig. 3 is a detail section.

I prefer in practice to have my improved bed-bottom comprise twosections A, which are connected in a hinged manner at B, so as to permitof it being folded upon itself in the ordinary manner for convenience inshipping or transportation. I do not desire, however, to be understoodas confining myself to the embodiment of the invention in a foldingbottom, and will therefore describe the same in terms sufficiently broadto cover the bottom when formed in one section and also when formed intwo or more sections.

O designates the base of the bottom, which may be of any suitableconstruction, although I prefer to form it of connected metal straps a,as shown.

D designates the lower horizontal series of vertically-disposed coiledsprings, which are preferably increased in diameter from their lower totheir upper ends and have their lower ends connected to the base O,preferably by being passed through apertures l) in the straps a, asshown.

E designates the upper horizontal series of vertically-disposed helicalsprings, which are preferably increased in diameter from their middlesto their opposite ends and are by preference so arranged that each onewill bear upon the upper end of one or two of the lower springs D.

F designates the preferred connection for the upper ends of the springsE, which is a mat or cover formed of woven-wire fabric and arranged uponand connected to the upper ends of the springs E and also arranged in aframe G, of metallic rods or other suitable material; and II designatesthe continuous fabric of woven, laced, or linked wire, (preferably wovenwire,) which is interposed between the lower and upper series of springsD E and has its meshes arranged to receive the contiguous ends of saidsprings, as shown, so as to securely connect it to the same. As will bereadily observed, the fabric II forms a yielding platform interposedbetween and connected with the lower and upper series of springs andadapted to support the upper springs, whether the same are arranged invertical alinement with the lower springs or not. This interposedflexible fabric H is preferably arranged in a frame I, of metallic rodssimilar to that inclosing the mat F, and in addition to forming asupport for the upper springs E it has for its purpose to steady bothlower and upper springs D E and effectually prevent the same from movinglaterally or wabbling when weight is imposed upon the bottom, which isthe chief objection of those spiral springs which extend the full heightof a double-decked bottom and are tied together at their middles. \Vhileperforming the functions just stated in an efficient manner, the fabricII permits each of the lower springs D to give independent of thesprings around it when weight is imposed on the particular spring orsprings above it, and thus contributes materially to the springiness andease of the bottom and renders the same greatly superior to thosebottoms in which a rigid frame, of wood or other material, is interposedbetween lower and upper horizontal series of springs, with the resultthat when weight is imposed on one of the upper springs it isdistributed among several of the lower springs, which detracts from thespringiness of the bottom.

As best shown in Fig. 2, the mat F is by preference connected to theupper ends of the springs E in the same manner that the fabric ll isconnected to the springs D E-i. 6., by having its meshes arranged toreceive the upper ends of said springs E.

The fabric II and mat F are preferably provided with strap stays c,which extend through their meshes and are connected to their frame rods.Said fabric and mat are also preferably made of a greater width than thebase 0, so as to overhang said base, as shown, and adapt the bottom foruse on metallic bedsteads. Vhen, however, the bottoms are to be used onwooden bedsteads, the base 0, fabric H, and mat F will be made equal inwidth.

It will be appreciated from the foregoing that I have provided a high ordouble-decked mattress which while possessing the advantages stated isvery simple and may be quickly and easily made entirely of metal, ifdesired.

Having thus described my invention, what I claim is 1. Theherein-described double-deck bedbottom comprising a suitable base, thelower horizontal series of vertically-disposed spiral springs connectedto and rising from the base, the upper horizontal series ofverticallydisposed spiral springs, the flexible wire fabric H arrangedbetween and connected to the adjacent ends of the lower and uppersprings and forming a yielding support or platform for the upper springsso as to permit of said springs being arranged in or out of alinementwith the lower springs, and a suitable means for connecting the upperends of the springs comprised in the upper horizontal series,substantially as specified.

The herein-described bed-bottom comprising the base, the lowerhorizontally-disposed series of vertical springs connected to and risingfrom the base, the upper horizontally-disposed series of verticalsprings, the woven-wire mat arranged in a marginal frame G and havingits meshes receiving the upper ends of the upper springs whereby it isconnected of itself to the same, and the woven-wire fabric 11 arrangedin a marginal frame I and interposed between the lower and upper seriesof springs so as to form a platform or support for the upper springs andhaving its meshes receiving the contiguous ends of the lower and uppersprings whereby it is connected of itself to the same, substantially asspecified.

In testimony whereof I affix my signature in presence of two witnesses.
